Abstract: A package for storing and dispensing potentially dangerous materials, such as medicament tablets or the like, said package being resistant to opening by children but readily openable by adults, particularly adults having impaired manual dexterity of their hands and/or fingers. In a particularly preferred embodiment, the package comprises a bottle (12), a collar (32) which is secured in place over the uppermost portion of the bottle (12) and a closure (52) which is secured to the finish portion of the bottle by means of complementary screw threads. The collar (32) preferably includes a pair of resiliently deformable spring-like pushtabs (34) containing vertical extensions (36) which engage interlocking teeth (62) on the innermost surface of the closure skirt (60) when the closure (52) is fully assembled onto the bottle (12). To remove the closure (52) , the opposed pushtabs (34) must be manually depressed prior to applying unscrewing torque to the closure (52) to disengage the pushtab extensions (36) from the interlocking teeth (62) on the closure (52). In a particularly preferre d embodiment, the spring-like pushtabs (34) are generally outwardly directed prior to application of the closure to the package. Advancing the closure (52) onto the package until the teeth (62) on the innermost surface of the closure's skirt (60) interlock with the vertical extensions (36) of the spring-like pushta bs (34) causes a degree of resilient deformation of the spring-like pushtabs (34) s o that the vertical extensions (36) of the pushtabs (34) are in contact with and exert a preloading force against the corresponding innermost surfaces of the clo sure skirt once the closure has been securely applied to the package. Quite unexpecte dly, it has been learned that preloading the vertical extensions of the reiliently deformable spring-like pushtabs against the corresponding inner-most surfaces of the closure skirt in the foregoing manner considerably enhances the child resistance of the package without increasing the difficulty of opening for older adults or those having impaired manual dexterity. Methods for producing the improved package are also disclosed.

Abstract: In an optical-fiber gyro for detecting a rotational angular velocity by a Sagnac phase difference of light signals propagated through an optical-fiber sensing loop, no polarizer is used, and a light source having a difference in attenuation or amplification factor between two orthogonally-polarized light streams is used.  Alternatively, a light source is optically-coupled to an optical coupler for supplying two divided light signals to the sensing loop and for receiving the two light signals after their propagation through the sensing loop in an optical fiber of a predetermined length.   The length of the fiber is set according to a relationship in which a distance difference determined by the predetermined length and a phase difference  of  two  orthogonally-polarized  light  streams propagated  through  the  optical  fiber  is  greater  than  an interference distance of the light source.

Title: Cleaning wash-arm for dishwashing filter
Inventor: KIRKLAND DANIEL R
IPC: A47L15/23
Filed: 1994-05-03
Granted: 1996-10-15
Abstract: The present invention provides a wash arm for a dishwasher which includes first and second openings which simultaneously propel the wash arm and rinse or back-flush filtered debris from a filter. The filter includes a settling chamber and a mesh screen, the mesh screen defining a portion of the top surface of the settling chamber and including inner and outer surfaces. Wash water flows through the mesh screen from the inner surface to the outer surface, causing filtered debris to be retained or trapped on the inner surface of the filter . The openings in the wash arm are downwardly and outwardly directed, and supply rinsing jets of wash water which impinge upon the outer surface of the filter and rinse retained debris from the inner surface thereof. The rinsed debris is thereafter held and suspended within the settling chamber until the dishwasher is drained. The pair of openings are radially displaced first and second distances from a center of the wash arm. Reaction forces produced by water exiting the openings combine or cooperate, resulting in a net reaction force which rotatably drives the wash arm about its axis of rotation at a predetermined rate.

Abstract: A system which avoids the bandwidth inefficiencies of simply providing multiple separate and independent channels for distributing data services over television compatible networks by considering the multiple channels as one unit and managing them as one unit with an upstream bandwidth management unit. This bandwidth management unit dynamically assigns active users to unused bandwidth among multiple channels. To accomplish this, the bandwidth management unit records each request for channel bandwidth that is made, each request that is being actively fulfilled, and each request that has been completed. Thus, data serviceproviders, such as multimedia services, can efficiently use multiple 6 megahertztelevision network compatible channels to distribute their data to many requesters/users at high rates of speed over a relatively inexpensive existing network.

Abstract: Mounting flange for a mounting fixture for mounting wheels from different makes of motor vehicles on the shaft of a balancing machine. The mounting flange has multiple sets of centering holes lying on concentric circles surrounding the central guide hole for axial guidance of the flange on the shaft of the balancing machine. The centering holes receive centering pins terminating in conical ends which fit into the mounting holes in the automobile wheel being balanced. The centering holes of each set are identified by an appearance different from any other set, provided by a configuration or color in a depression in the surface of the mounting flange surrounding the centering hole. Thus, all the centering holes that belong to the same set can be quickly identified when inserting the centering pins. Because the identifying indicia are recessed, they are protected from wear and damage.

Title: Medication vial/syringe liquid/transfer apparatus
Inventor: PETERSON STEVEN F
IPC: A61J3/00
Filed: 1996-12-11
Granted: 2000-06-27
Abstract: Liquid-transfer apparatus, and methodology employing the same, operatively interposable a syringe and a vial, and accommodating both a single-mouth-size (single-size), two-vial transfer procedure, and a two-mouth-size (two-size), two-vial transfer procedure. The apparatus includes a liquid-transfer device having a syringe-coupling end, a vial-coupling end, and liquid-passage structure effectively communicating between these ends. In the case of accommodating a single-mouth-size (single-size), two-vial procedure, only the liquid-transfer device is employed, and the same is sized with a vial-coupling end that is constructed for direct coupling to the top of the single-size vial which is used. In the case of accommodating a two-mouth-size (two-size), two-vial operation, the liquid-transfer device is employed along with a vial-coupling adaptor which is removably receivable in a connected relationship with the vial-coupling end in the device to adapt the same for coupling to the top of a vial having the smaller of the two sizes of vials which are to be employed. Under these circumstances, the entire procedure begins with coupling of the apparatus to a syringe and to the smaller-size vial, with the vial-coupling adaptor connected to the liquid-transfer device's vial-coupling end. Following a liquid-transfer operation with this smaller vial, the same is decoupled, and such decoupling automatically disconnects the vial-coupling adaptor and the liquid-transfer device. Thereafter, a vial of the larger size is coupled to the vial-coupling end in the liquid-transfer device, and a transfer procedure is completed between the syringe and the larger coupled vial.
